Title:
無線移動通信システムにおけるMBMSデータのための制御信号伝送方法
Document Type and Number:
Japanese Patent JP4829990
Kind Code:
B2
Abstract:
A method of receiving a multimedia broadcast/multicast service (MBMS) service by a mobile terminal, comprising: reading a first channel to receive information about a second channel; reading the second channel to receive information about a third channel; and reading the third channel to receive the MBMS service, wherein the first channel is a broadcast control channel (BCCH), the second channel is a control channel for the MBMS service, and the third channel is a traffic channel for the MBMS service, wherein the BCCH is used to receive system information, wherein the first, second and third channels are logical channels that are located between a Radio Link Control (RLC) layer and a Medium Access Control (MAC) layer, wherein the second channel is used to receive MBMS control information related to a point-to-multipoint (p-t-m) MBMS radio bearer (RB), wherein the MBMS control information comprises p-t-m MBMS RB configuration information, wherein the p-t-m MBMS RB configuration information includes channel information and layer information, wherein the channel information is related to a transport channel which is located between the MAC layer and a physical layer, and a physical channel, wherein the layer information is related to at least one second layer which is below a radio resource control (RRC) layer, and wherein the at least one second layer comprises a packet data convergence protocol (PDCP) layer and the RLC layer.
